SPECIFICATION forming part of Letters Patent 0.380,024, dated March T27, 1888.

Application tiled November 16, 1887. Serial No. 255,287. 4(N0 model.)

To aZZ whom it may concern:

Be it known that we, DENIS M. DENEHY and HEMAN W. CHILDS, citizens of the United States, residing at Acampo, in the county of San Joaquin and State of California, have invented `certain new and useful Improvements in Platform-Scrapers; and we do hereby declare the following to be' a full, clear, and exact description of the invention, such as willenable others skilled in the art to wh1ch 1t appertains to make and use the same, reference being had to the accompanying draw- 1ngs, and to letters or igures of reference marked thereon, which form a part of this specification.

Our invention relates to certain improvements in that class of earth-Scrapers used for grading and leveling oil' land and for ditching purposes; and it consists in the combination of certain parts, as hereinafter explained, and pointed out inthe claims.

Referring to the accompanying drawings, Figure l is a side elevation of our scraper. Fig. 2 is a plan of the same.

- The platform A is suitably mounted on front bearing-wheels, A', and axle A3,and the rear4 is supported by pivotally-attached wheel A2. To the axle A3 are attached forwardly-extending arms B2, which are coupled to the scraper B by means of ears B', attached at the back 'of the scraper and cross-rod B. To the outside of the front of the scraper Bare attached ears b', to which 'are attached forwardly-extending arms B3, embracing the pole or tongue B5, to which the team is attached.

The position and operation of the scraper B are controlled by a system of levers composed of a lug, b, attached to the top of the back of the scraper, which is connected by a rod and chain, d, to a lever, D,'with a halfcircle foot, D, having a grooved face carrying the chain d and having its fulcrum upon a post, H, whose foot is attached at the centerof the platform A. The foot D has its bearing upon a pin,

F, secured to post H. A post, E, is attached to the front of the platform. A half-circle, G, has its rear end attached at the rear of post H to the platform and itsfront end to the post E, and is likewise secured to the post H, serving to` brace the two 'posts firmly and likewise as a stop for the lever D in its various positions, being provided with three lugs, h, the center one of which serves to secure the half-circle Gto the post H, and is likewise provided at its other end with'a hook, z', which holds a lever, G', when the scraper is elevated, which lever has a half-circle foot with a grooved face carrying a chain, c, which is attached to the cross-rod B4 at its center. c

Theaboyedescribed system of leverage controls the position of the scraper B, the lever C C being more particularly used to dump the load of earth and elevate the scraper for purposes of transportation.

Having thus described our invention, what we claim, and desire to secure by Let-ters Patent, is-

1. The combination, substantially as described, of the vehicle A A A2 Aa and lever devices consisting of the posts H and E, the half-circle G h, the levers D D and C C, the

chain and rod d, and the chain c,with the l scraper B, by means of the arms B2, attached.

forwardly-extending arms B2, attached to the axle A3 at their rear ends, and suitable levers for controlling `and operating the scraper, all substantially as set forth and described.

3.-The combination, with the platform A, suitably mounted and having attached to it the scraper B in front, of the posts H and E, and the half-circle G, provided with the lugs h, the center one of which is attached .to post H and is provided with an outside hook end,

i, engaging with the stad of the lever()` C, such lever being suitably connected with the scraper B by the chain c, all as shown and described.

4. The platform A, suitably mounted and Y connected with the scraper B by thetarms B2, attached in the rear to the axle A3 and in front to the ears B of the scraper by means of the cross-rod Biu combination with-the post E, the lever C C', ttached to such post, and the chain c, attached at its upper end to lever-shaft C and at its rear end to oross-rod B, all as set forth.

In testimony whereof We ax our signatures in presence of two witnesses.
